The cheaper the LED unit, the shorter its life. I have a friend who simply will not buy an LED unit made in China. Only US or EU countries. Which really limits availability and really drives up the price.
At this point I have no experience - either in my house (where I refuse to pay the exorbinant prices regardless of outrageous claimed bulb lives) or for growing plants. At some point, I may get a small unit to experiment.
I do hope yours work well for your application.
FWIW - I priced out systems and for me to replace all my current lighting with LED systems for the same area would be well North of a Thousand dollars. My current lights work fine.
